SIGNAL FOB REFRIGERATOR PANS.

Application filed. August 10, 1921. Serial No. 491,306.

To all whom it may condemi Bc 1t known that 1, Louis WnrrzMAN, a

citizen of Russia, and resident of Milwaukee,

in the county Off Milwaukee and State of i isconsiin, have invented certain new and useful Improvements in Signals for Refrigerator Pans; and I do hereby declare that the folio-win is a full clear and exact dea a v a thcreot on the scription thereof.- 1 p h y invention relates to a. new and improved signal which is adapted to be used in connection with reifrigerator pans, such as are used to catch the drainage from the.

oi the arm which carnes the hammer 10 and melting ice.

These pans are generally of small size and must he tt'rcqu'ently emptied in order to prevent the same from overflowing. This is frequently "forgotten with the result that the pan overflows and causes considerable damage, especially when the refrigerator is located on one of the upper floors of the building, due to the leakage of the water through the ceiling of the room below.

The generalobject of the invention is to provide means which may be readily applied to the pan and which will automatically give an alarm to notify the occupant that the pan requires emptying;

A further object of the invention is to pro- "ide a device of this kind which may be easilyadjusted to accommodate it to a pan of any size which is likely to be used.

I A. devicewhich comprisesmy invention is illustrated in the accompanying drawing, in which i Figure with the cover removed.

l igure 2 is a longitudinal sectional View iine 2--2 of lfigure 1.

l igurofl is a cross sectional view on the line 33 of Figure 1. i

, The device includes a pair of sliding Frames Land 2 which may be connected. in

any suitable manner such asthe tongue and groove connection shown at 3. This permits the'frames to be adjusted to accommodate the device to the size of thepan i on which it is to be placed. One of the frames is provided with a housing 5 which is provided witha suitable cover 6. The housing is providedwith suitableopenings 7 to permit the 1 a plan view of the invention water to flow, into the same and the cover is provided with an air opening 8. A bell9 is suitably supported within the housingand a hammer 10is pivotally mounted at 11 to cooperate therewith. The usual alarm operating mechanism is provided in the portion 12 ot' the housing and may be wound by means of a key 13. An arm 14 ispivoted at 15 and is offset at 16 sov that the outer end extends into the interior of the pan t and is provided with a float 17 oil? cork or other suitable material. A finger 18 is formed on the arm and normally extends into the path prevents it from operating. It will readily be seen however that when the water in the pan rises so as to be in danger of overflowing the float 17 will rise and cause the finger 18 to release the hammersoas to give the alarm.

I claim as my invention: v

1. A device of the character. described comprising a support, an alarm mounted thereon and including abell, a pivoted hammer for striking the bell, and means for op erating the same, said support comprising two members slidable with respect to each other to adapt the same to span pans of different sizes, an arm pivoted to the support and having a finger normally extending into the path oi the hammer to prevent the operation thereof, the end of said arm being extended into the pan and having a float OP:

'erable when the pan is filled with liquid to a predetermined level to raise the arm and finger and release the hammer.

tion within said pan and to support said lloat when it is in its lowest position.

In testimony that 1 claim the foregoing have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

LOUIS WEITZMAN.
